' COIL-WINDING MACHINE.

Application filed January 4, 1921. Serial No. 435,000.

To all whom it may concern:

Be it known that 1, CHARLES FAYER, a citizen of the United States,residing at New York, county of New York, and State of New York, haveinvented certain new and useful Improvements in Coil-Winding Machines,of which the following is a full, clear, and concise description? a, Myinvention relates to coil winding machines; that is, to machines'us'edfor the purpose of winding coils of the type used for producinghightension currents, impulses and discharges, and. particularly suchcoils as are employed in radiographic and X-ray work.

More particularly stated, my invention contemplates improved mechanismfor automatically stopping and starting the winding drum, and for soregulating the distribution of the wire as wound thereupon as to causethe stoppage of the drum to take place at exactly the proper instantrequired by the distribution of the wire upon the drum. That is to say,I make specific provision for the drum to stop turning at the instantwhen the wire, as wound upon the drum, is completely formed into a layerof a single thickness of the wire. 1

My invention further contemplates the arrangement and adaptation of themechanism just mentioned, for use in connection with other mechanism,controllable directly by hand, for winding upon the drum afillet orribbon of paper or other flexible, insulating material, and for cuttingoff this fillet pe riodically. inorder for it to be formed into bandsdisposed concentrically, without .interfering with the continu'it'y'ofthe wire, or with the proper distribution of the convolutions thereof.-

My invention further contemplates an improved stop-motion, speciallyadapted for use with mechanism of the kind above mentioned.

Reference is made to the accompanying drawings forming a part of thisspecification, and in .which. like letters indicate like partsthroughout the several figures.

Figure 1 is a side elevation of my improved coil winding machine.

Figure 2 is an end elevation of the same. Figure 3 is a diagram of thewiring, and

parts immediately associated therewith.

Mounted upon a base plate 4 are a number of posts 5, 6, 7 and 8, and aframe 9. These parts being used for supporting-various portlons of themechanism. The'frame is provided with slots 10, 11 arranged in pairs andareused for supporting rolls of paper 12, 13, the slots 10, 11 being forthe purpose of facilitating the removal and replacement of the rolls ofpaper. Strips 14:, 15 are wound off of these rolls of paper and formedinto fl a fillet 16, which is thus of two ply, paper. Either or both ofthe strips of paper 1 1, 15 may be prepared with an adhesive surface for'thls purpose. The fillet 16 passes between a pair of presser rolls 17 Ashear 18 is provided for the purpose of severing the fillet 16 atintervals, thus cutting it into lengths as desired.

A winding drum is shown at 19, and is used for supporting the coil aswound. This drum carries a cylinder 20, of fiber orother insulatingmaterial. The drum is supported upon a revoluble shaft 21, and isprovided with a pair of end guards 22, 23, eachhaving the proximate formof a disk.

A brace 24 is mounted upon the posts'6,

7 and is secured to bearings 25, 26 with 'which these posts areprovided. A counter is shown at 27, and 18 mounted upon the brace 24,the latter serving as a'beam for supporting the counter."

Mounted upon the shaft 21'is a pulley 28 for communicating motion toother parts as hereinafter described.

A starting box 29 is mounted upon the post 5. VVires- 31, 32, preferablyformed into a cable 33 lead from a source of electricity, not shown, tothe starting box 29.-

A pair of wires 34, 35 lead from the starting box 29 to the counter 27,for the purpose.

of enabling the counter to automatically control the starting box, ifthis be'desirable.

The starting box is provided with a push button 30 and a 'main switch32.

An electric motor is shown at 36, and is provided with a sleeve 37servingas a beargrip handle 39 and shifting the same to the right orleft so as to causethe clutch pin 4-1 to enter or leave the slot 40, canthrow the shaft 21 into or out of working relation with the electricmotor 36. A wire 42 leads from the push button in the starting box 29 tothe motor 36, and a wire 43 leads from the main'switch 32 to a bindingost 46 carried by a circuit breaker 48. nother binding post 47 iscarried by this circuit breaker, and connected with this binding post isa wire 44, A wire 44 is connected gear 54. carries a pair ofpresser pins55,

56, disposed diametrically opposite each other and each located adjacentthe edge of the gear.. A contact member 57 extends through and-issupported by a plate 58 of insulating material, and a'c'ontact member 59is mounted upon and carried by an arm 60. The arm 60 is made of metal,and

is mounted upon a bearing 61. The arm 60 carries a presser knob 62,which is rounded as shown in Figure 3, and located partially in the pathof travel of each of the presser pins 55, 56. The parts just describedare so formed and arranged that either one of the presser pins 55, 56,coming into engagement- .with the presser knob 62, causes the arm 60 toswing slightly in a clockwise direction according to Figure 3, and thusmove the contact member-59 out of engagement with the contact member.57. A spring 63 is used for the purpose of shifting the armfiO-back intoits normal position-that is into such position that the contact member59 is in engagement with" the contact member 57.

The worm gear 54. carries a heart cam 64, and engaging this. heart camis a pin 65, carried by a swinging arm 66. A spring 67 engages the pin65, and constantly presses the same against the edge of the heart cam.The spring 67 is mounted uponastationary arm 68.

The swinging arm 66 has the form indicated more particularly in Figure1,- and is provided with a slot 70. The swinging arm 66 carries abearing 71, which is slidably adjustable along the upper portion of thearm, by aid of ,the slot 70. The bearing 71 carries a pulley 72, whichis 'thus adjustable relatively to the swinging arm and supportedthereon. V

Mounted upon the post 8 is a bearing 7 3*, carrying an arm 75, thelatter supporting a spool 74. A wire 73 is reeled 06? from the spool,and'passes over a pulley 76'and under the pulley 72, being thence woundaround the drum 19, as may be understood from Figure 2.

The pulley 76 is carried by a pulley block 77, and this pulley "block issupported upon a cord 78, the'cord being partially wound around 'alifting drum 79. This drum is supported by a stationary shaft 80. Thecord 78 carries a tripping block 81, which may be broughtinto'engagement with a contact arm 82 whenever the cord 78 is wound upand the pulley 76 thereby raised by means of the lifting drum 79.

A tubular block 83 serves as a limiting stop for preventing excessiveupward travel 'of the contact arm 82,- as may be understood,

from Figure 3.

The contact arm 82 carries a plate 8-l,

and from the latter a guide rod 85 extends downwardly. Looselyencircling this guide rod is an eye 86, carried by the pulley block 77.By this arrangement the'pulley block 77 is'in its up and down movementsguided by the guide rod 85, 'so as to cause the tripping block 8, in itsupward travel, to

be brought accurately and positively into.-

engagement with the adjacent end of the contact arm 82, as indicatedmore particularly in Figure 3. l

" The contact arm 82 carries a contact boss 87, and adjacent the latteris another contact boss 88. The contact boss 88 is mounted upon ametallic strip 89, and mounted upon this strip is" a binding post 90.The strip 89 and another binding post 91 are mounted upon ,a board 92.The contact arm 82 is pivotally supported below the board 92, and isengaged by a spring 93, whereby it'is always maintained under a gentletension. Thus the "contact-consisting ofthe bosses 97, 88' isnormally-"closed, but is opened whenever the'fpiilley block 77 is raisedto its upper limit of travel. The board 92 and parts immediatelyassociated therewith are supported by a stationary arm 94, the latterbeing mounted 11 upper portion of the post 8. I 1 For the purpose ofproperly tensionihg' and centering the spool 74 I provide a plunger 95,encircled by a spring 96 and extending through a sleeve 97. This sleeveis pro vided -with an arm 99, and extending through a'hole in the latteris a guide rod 98.

The wiring emplpyed is shown diagrammatically in Figure 3, The board 92with its accompanying parts includin the contact arm 82 is essentiallya-circuit breaker, and this circuit breaker is in series with thecircuit breaker 48, which is provided asabove explained with the contactarm 60.. Thus the circuit ofthe system contains two contacts arranged inseries with each other and with the motor 36, and so arranged .that theopening of either contact will stop pen the" 32*, wire 32 to source ofelectricity, not shown, and thence back to wire 31.

If, however, the circuit just traced happens to be open owing tothe'positlon occupied by either of the contact arms 60 or82, so that themotor is not energized, the push button 30, contained in the-startingbox 2% mav be closed by hand and another circuit thrbugh the motor maynow be traced as follows: wire 31, motor .36, wire 42, push button 30,main switch 32, wire 32 to source of electricity, not shown, thence backto wire 31.

The swinging arm 66, the heart cam 64 and various other partsimmediately associated with these parts are so proportioned andarranged, relatively to the drum 19,

, that each complete swing of the arm 66 cated carries the pulley 72 adistance approximating the width of the drum 19. Slnce,

however, it may happen that coils of different sizes areto be wound uponthis drum,

or in other words since the drum may be virtually wider at one time thanat another,

the distance traveled by the pulley should.

be varied accordingly. The operator by adjusting the position of theslide 71 may within reasonable limits vary the length of the stroke ordistance of travel of the pulley 76.

The operation of my device is as follows:

The various parts being assembled and arranged as above described, andbeing in their respective normal positions, the device is operated asset forth below.

I will assume that the electric motor is running, and that the swingingarm 66, the heart cam 64 and various other movable parts occupy therespective positions indifor them in Figure 3. The swinging arm '66 isnow swinging to the right according to this figure, and the heart cam isturning in a contra-clockwise direction,

so that the presser pin 56 is approaching the presser knob 62 and thepresser pin 56 is recedlng therefrom. By the time the swinging arm 66reaches the limit of its travel to the right, the presser pin 56 engagesthe presser knob 62 and rocks the arm in a clockwise direction, so thatthe contact mem ber 59 is moved out otlenagagement with the contactmember 57. This breaks the motor circuit and thereby stops the motor,

so that the various movable parts are brought to a standstill.

The swinging movement of the arm 66 to the right, as just described,carries the pulley 72 to a distance corresponding to the width of thedrum 19, so that thewire 7 3 is so delivered to this drum and so woundthereupon as to form a single unbroken layer. hen the motor stops asjust stated, the operator brings the end of the fillet 16 into contactwith the layer of wire just wound upon the drum 19, and by turning thedrum a single revolution by hand, coils the'fillet upon the drum, soasto form a band or ring, the end of the fillet being overlapped byanother tportion of the fillet. The operator then actuates the shear 18,and severs the fillet, the, portion thus cut off being of course sodisposed as to completely cover the layer of wire. The wire 73 is notsevered, however. The operator next starts the motor into action, andfor thispurpose closesv the push button 30, or in other wordsshort-circuits the 'circuit breakers. This is only for an instant,however, because as soon as the motor begins to run therotation of thegear wheel 54 carries the presser pin 56 out of engagement with thepresser knob 62, so that the arm 60, under pressure from the spring 63,now rocks slightly in a contra-clockwise direction and this brings thecontact member 59 into engagement with the contact member 57. Thiscloses the motor circuit independently of the push button 30, so thatthe motor continuesrunning after pressure upon the push buttonisrelaxed. The motor continues running until the presser pin 55 engagesthe presser knob 62 and thus causes the arm 60 to rock slightly asbefore and again open the motor circuit, stopping the motor as before.Thus the swinging arm 66 swings first to the right and stops, and thenswings to the left and stops, each swing of the 'arm in either directionresulting in a single layer of wire being wound around the drum, theoperator being allowed time, after the layer is in position, to windaround it a fillet of paper or other flexible insulating material.

Suppose, next, that the wire 7 3 breaks from any cause, usuallyaccidental, or that the wire becomes exhausted. This frees the pulley76, heretofore held down in its normal position by the tension of thewire, and as a result the pulley block 77, carrying the pulley 76, islifted upward by means of the lifting drum 79, acting upon the cord 78.As the pulley block 77 rises, .the tripping block 81 engages the contactarm 82, and by rocking it slightly as indicated in Figure 3, moves thecontact member 87 out of engagement with the contact member 88. Thisopens the motor circuit and stops the motor and all movable parts driventhereby.

The operator may now start up the motor by pressing upon ,the pushbutton 30, .so as to short-circuit the circuit breakers as abovedescribed, and the motor thus started 'will .plied and properlyconnected, closure ofthe push button starts up the motor and the lattercontinues to run until stopped as above' described by the opening of themotor cir-' cuit when the arm 66 is at the limit of its travel in eitherof two directions; in other words, until either the presser pin or thepresser pin 56 engages the presser-knob 62 and rocks the arm 60. g I donot limit myself to the precise mechanism shown and described, asvariations may be made therein without departing from the spirit of myinvention, the scope of which is commensurate with my claims.
